Abstract

A pioneering experiment in Λ hypernuclear spectroscopy, undertaken at the Thomas Jefferson National Accelerator Facility (JLab), was recently reported. The experiment used the high precision, continuous electron beam at JLab, and a special arrangement of spectrometer magnets to measure the hypernuclear spectrum from C and Li7 targets using the (e,e'K+) reaction. The Λ12B spectrum found in this investigation was previously published, but is reported here in more detail, with improved resolution. In addition, the results of a Λ7He spectrum also obtained in the experiment, are shown. This latter spectrum indicates the need for a more detailed few-body calculation of the hypernucleus and the reaction process. The success of the experiment demonstrates the potential of the (e,e'K+) reaction for high resolution spectroscopy of hypernuclear spectra.
